From the Knit Picks Website:

In a misty grey color, these legwarmers are a combination of lace (thus the holey) and wispy, rising cables (thus the smokes).

The cashmere is simply wonderful against bare skin…equally a luxury over tights. You’ll love the way Capra works up, how its softness feels in your hands as you knit and whenever you wear these cozy accessories. The cables have enough stretch to wear either over the knee or under.

Holey-Smokes! can also be worked shorter - as short as just the Wind Pattern cuff if you please - for use as boot toppers.

Needles:
Size 5 (3.75mm), Size 6 (4.00mm), and Size 7 (4.5mm): DPNs
Size 5 (3.75mm): straight or circular (optional)
